Seehafen Kiel GmbH, the port of Kiel, Germany, has commissioned Siemens AG to construct two additional ‘Siharbor’ shore side power plants at Kiel’s Ostuferhafen. The construction project, with a total investment value of approximately €17 million, comprises a 50/60 Hz shore power plant for cruise ships and ferries and a 50 Hz plant for ferries. It means that the power supply ships need while they are in port can be sourced from renewable energy on shore instead of diesel generators on board. The new shore power connection will be one of the largest installations of its kind in Europe. Once the project is completed in 2023, the port of Kiel will be able to supply green power to six ships simultaneously at all of its major passenger, cargo and ferry terminals.
